中文摘要：
以苯甲醇为溶剂和还原剂,溶剂热法一步合成四氧化三铁/石墨烯-碳纳米管（Fe3O4/r-GOCNTs）三元复合材料。X射线衍射仪（XRD）、傅里叶红外光谱（FTIR）、扫描电子显微镜（SEM）和高倍透射电镜（HRTEM）测试显示,Fe3O4纳米晶体的生成与氧化石墨烯的还原是同时发生的,Fe3O4的尺寸约为10 nm,均匀且稳固地生长在r-GO片层和CNTs组成的三维网络结构上。电极材料在0.1 A/g下循环100次之后可逆比容量为840 mA·h/g,循环稳定性明显优于纯Fe3O4电极。
英文摘要：
A one-pot process for preparing Fe3O4/r-GO-CNTs composites has been realized. In the sol- vethermal process, benzyl alcohol was used as the solvent and reducing agent. The morphology and struc- ture of the composites were characterized by X-ray diffraction （XRD） , Fourier transform infrared （FTIR） spectroscopy, scanning electron microscope （SEM） and high-resolution transmission electron microscope （HRTEM）. The results demonstrated that the reduction of graphene oxide and the deposition of Fe3O4 a- bout 10 nm on r-GO-CNTs surface were occurred simultaneously. The cycling stability of the obtained hy- brid is better than that of the pure Fe3O4 electrode material. At the current density of 0. 1 A/g, after 100 cycles, its reversible discharge capacity still remained 840 mA.h/g.
